Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed form the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure (基礎(chǔ)設(shè)施) that must be maintained.

       Unfortunately, these systems are starting to break down. It’s not just in Yosemite but in national parks around the nation.

       Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The Park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.

       Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipes almost broke again and roads had to be closed for a while.

       Why hasn’t the National Park Service kept up the park repairs? There is a lack of money. The United States has 378 monuments, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.

       Yosemite is one national park that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.

       A sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded park.

Millions of youngsters across Europe could suffer permanent hearing loss after five years if they listen to MP3 players at too high a volume for more than five hours a week, EU scientists warned.

The scientists’ study, requested by the European Commission, attacked the concept of “l(fā)eisure noise,” saying children and teenagers should be protected from increasingly high sound levels---with loud mobile phones also coming in for criticism（批評(píng)）.

“There has been increasing concern about exposure from the new generation of personal music players which can reproduce sounds at very high volumes without loss of quality,” the Commission, the EU’s executive arm, said in a statement.

“Risk for hearing damage depends on sound level and exposure time,” it said. More and more young people were exposed to the great threat(威脅)that leisure noise posed to hearing, it said.

Commission experts said that between 50 and 100 million people listen to portable music players on a daily basis.

If they listened for only five hours a week at more than 89 decibels(分貝), they would already be beyond   EU limits for noise allowed in the workplace, they said. But if they listened for longer periods, they risked permanent hearing loss after five years.

The scientists calculated the number of people in that risk category at between five and 10 percent of listeners, meaning up to 10 million people in the European Union.

Sales of personal music players have soared in EU countries in recent years, particularly of MP3 players.

"I am worried that so many young people ... who are frequent users of personal music players and mobile phones at high acoustic levels, may be unknowingly damaging their hearing ," she said in the statement.

Which of the following can be the best title of the article?

A. Youngsters across Europe: suffer permanent hearing loss.

B. MP3 players: sell best but do harm to youngsters

C. The scientists’ study: requested by the EU

D. EU warns youth: turn your MP3 players down!
